Specification of Letters Patent.

lPatented July 14, 1908. l

Application filed December 31, .1907.' `Serial. No. Y10,751.

To'cll whom tif/nay concern.'

Be it known that we, JOSEPH CALVIN and for the track rails, which latter areheld in place on the seat blocks by rail holding plates resting in recesses in the cross tie `and firmly secured b bolts passing therethrough and through sai cross tie. l

Another object of the invention concerns the formation of the metal tie from a plate made of the proper size with the several recesses, projections and thicknesses); and then folded and pressed into -a hollow, closed, trunk-like structure ready to be placed in position to receivevthe seat blocks and rails.,

With these and other objects in View, the invention consists of the novel construction, combination and arrangement of parts hereinafter described and deiinitely claimed, reference being had to the accompanying drawings, in which y Figure 1 is a longitudinal sectional View of cured thereto.` Fig. 2 is a similar view,`

enlarged, of one end of the cmss tie with. a track rail thereon, the joint between two rails and their securing iish plates being shown, also the position of the rail when on `a curve in the track, and the rail bracing block. Fig. Sis a plan View of the right end ofthe cross tie illustrated lin Fig. 1, on an l enlarged scale. f Fig. 4 is` a perspective v 'iew of the blank from whichthe cross tie is formed, asv seen from the side which will lbelinner most when folded. Fig. 5 is a cross seotion through the cross tie on a plane coincident ,with that of the center of the rail. Fig. 6 is a detail view of one of the rail plates.

Similar characters of reference indicate corresponding parts throughout the drawings. The cross tie 1 is madeoi a plate 2 of metal,

I preferably malleable iron or steel, with all its depressions, recesses, differences in thickness and projections formed therein and thereonV while in the flat form, see Fig.y 4.` The sides and ends are then folded4 and pressed by suitable machinery i'nto a rectangular trunk-like` o r creeping with the rail.

lwards the center of curvature. .in connection with the .elevation given thev closed hollow body of theA correct length,

Ahei ht and width to form a railroad cross tie.

ear each end of the cross tie 1 is a transverse slot 3 extending wholly across the tie and of a width sufficient to receive' a block 4 of slightly resilient material, such as wood, capable of supportingr a track'railand the'l weight of passin .tra c. slot 3 is a small` -an e or rib 5- which prevents the supportingbloc 4 from movin'gendwise Beneatheach slot 3 and integral; with the top plate 6 of the.

cross tie 1 is afoot piece or bearing rib 7 resting within thecross tie on the bottom plate- 8 and forming a non-yielding support and brace for the cross tie under the stress of passtrains. p

' nthe longitudinal center ot the crossv'itie and on opposite sides of each slot Sis a recess 9 the bottoms of which recesses incline downwardly toward the slots opening into them a short distance above their bottoms. With'- in these recesses are placed the track holding plates 10, each plate having a lip 10 on its 1nner end to overlie the base flange of the railand,by means' of a bolt,`hold the rail' firmly on its seat block 4, and the rail-plate ri id in its recess. The bolts 11, which hol the track lates 10, pass u through the cros's tie from t e bottom and t r gh openings'in theplates andare fastened by nuts 12 yabove thev plates. The bolts have a polygonal shape At each end of the ho es in thebottom of the cross tie to prevent thebolts'i'otating when the nuts 12 are ap-r plied to orremoved from them. The nuts are prevented from working oli thebolts by pii1s`13 fitted to holes in the bolts above the nuts. Where the tracks curve, the upper faces of the seat'blocks 4 are inclined, as indicated in Fig. 2, to tilt the rails inwardly to outside rail, supplies amore effective base This tilting,

and safer track than when thejrails stand perpendicu ar to the' cross ties. Where 'joints'in the rails rest on a cross tie, ,the bot- .tom 'flanges 14 of the fish-plates 15 are notched to admit'lugs 16 on the inner ends ofthe rail lates4 10 below the lip 10a, as indicated in igs. 2 and' 6.

. i'. At wagon road crossings metal castin s or f blocks y1'7 are laced a ainstthe outsi e of the rails to assist the'w eels of vehicles over heads, the' screws passing through the blocks into the cross ties. p y Cross ties constructed as above described are' strong, firm, and give the necessary yielding support to -the .rails l'fastened thereto. Any wearor compression of the blocks which would tend to cause lthe rail lates 10 to loosen can be quickly correctedpby tighten- Af ingthe nuts 12 with avsuitable wrench. When ,it becomes necessary to renew a block,the rail plates are removed, andthe rail elevated sufficiently to permitthe block being lifted" 2O over .the flanges or ribs-at thevends of the ffslots. 3.

' We claimz- 1. A hollowinetal cross tie'formed ofa folded plate of metal havingitsy upper side thickened from end toend, andan integral lug near .each end of and within said'. tie

projecting downwardly Jfrom 'said thickened I v topl and resting on the bottom of said tieto i .support a superimposed rail. A

2. A hollow metal cross tie formed of' a folded plate of vmetal havin its upper sidey thickened' fromendto end, t inner end prof jections to' be folded down for .closing the end of the tie, integral lugs depending from said thickened top and resting on the bottom of the tie to support superimposed rails, and transverse slots each rovided with a flange at each end made iiitue thickened top above said lugs.

3. A hollow railroad cross tie having tra1isl verse slots each provided with a low flange at each end, a rail seat block 'fitted to each slot between said end ,llanges, rail ,lates seated in recesses on p osite sides o lsaid slotsand having lips'for iolding the rails onI the se-at blocks,y the bottoms of 4said recesses being inclinedfdownward towards said"slots,

bolts projecting upwardly through the cross tie and rail plates, and nutson said bolts l 4. A hollow railroad cross tie having transverse slots each provided with a low flange at each 'end and a, recess on each side of each ofsaid slots with an inclined bottom, a rail bearing on said .rail plates.

seat block iitted ineach slot between said end flanges, rail plates in said recesses each plate having an overhanging lip and a lug elow itadapted to engage with and hold a iisli' plate, and fasteningmeans for holding said -rail plates in their recesses.

5. A hollow inetal cross tie formed of a 'folded plate of metal thickened on its upper side and having integral lugs depending therefrom and resting on the bottoni to support superimposed rails, transverse slots iii said thickenedupper side over said lugs, re-

cesses in said upper side at .right angles to said slots, and means `for securing to said tie av rail inclined to a perpendicular to said tie.

In testimony` that we claim the foregoing as our own, we have hereto alixed our signatures in the presence of two witnesses.
